Observed Soil Moisture Percentile (50cm soil column)
The plots below show current observed soil moisture (50cm soil column) percentile distribution for stations from NRCS, SCAN, USCRN and WRCC. Percentile calculated using weibull plotting rank of current day's soil moisture among 20 years' same-date soil moisture (1998-2017), which is extended by using MOVE2 and Bayesian post-processing algorithm respectively, MOVE2 extension is conducted with a moving window of 31 days, Bayesian extension is conducted directly to the entire record. Please input the date you would like to see.
Station screening result and reasons
Station screening criteria: 1. At least 5-year observation record; 2. Not irrigation-affected 3. Pass bivariate test between station precipitation and soil moisture
Saved stations (44 stations)
Deleted stations, network and reasons: total observation record length less than 5 years; irrigation-affected; failed to pass bivariate test (173 stations)
